Out of politics your voice your vote and last night's rock them sock on Republican debate. Front runners Mitt Romney and Herman Cain got pummeled like we've never seen before it got personal but wasn't enough to shake up the race we'll tackle that question a minute. But first here's ABC's John Karl with highlights from the -- -- -- -- yet. I'm just really knew I didn't even look at that they actually got physical. That's what happened when -- every week after Mitt Romney on illegal immigration. Admit you lose all of your standing -- my perspective because you hired illegals. In your home and you -- -- about it for a year. I don't think I've ever hired an illegal in my life they wanted list are -- again you look at the -- you I'm just daily news I'm taking the newspaper I say I'm community of thirty you get used to play at WW would you miss Elliot plays Layla -- I just -- -- talking. -- -- -- Rick this couldn't have a couple of debates -- -- And I understand that is so -- did again. The truth five years ago illegal immigrants -- do yard work it Romney's home. But they were hired by any landscaping company that we wanted Romney later fired. You have a problem with allowing some of the tennis being mistaken about suggest. But if you -- -- become president of -- states -- -- people speak -- let me make it. -- it was his quite Steve's defeat yet. Came out swinging -- profit came to. Hammering -- 999 swimmers for imposing new sales tax permanent it's not been -- -- but in fact. Everyone hate -- over his 999 plan. The -- and analysis I did. Person by person returned my return is that middle income people see higher taxes and your plant the reason that album plan is -- -- attack so much is because. Lobbyists. Accountants. Politicians they don't want to throw -- the current tax code and put -- something that's simple and fair. Romney also took it from all sides but hammered over -- health care plan He. He put in place as governor of Massachusetts this is up and it was crafted from Massachusetts it would be wrong to adopt this. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- We're I don't know what what what party you're allowed so -- -- -- what you're out of time. Lot of time and. One point Perry bickered with the moderator you get to ask questions -- -- to answer like I want. -- and all the infighting was a bit too much for Newt Gingrich who warned Republicans could blow their chance of beating Barack Obama to the mayor's plan to join us that maximizing bickering has probably not the road to the White House. The biggest take away from last -- that Rick Perry is not going to go away quietly. He was more aggressive and combative than ever and He showed that He is going to try to fight his way back the way He is one time after time in Texas. By going for the jugular.
